Traveling by Underground Train

The audio begins with the low hum of an underground train, a fusion of the rhythmic clatter of wheels and the distant echo of the subway's hustle and bustle. This is not just a train; it's a metro, an underground transportation system that symbolizes the pulse of the city it serves. The hushed whispers of people in conversation and the occasional rustle of newspapers punctuate the steady roar of the train. The soft ding of the train's bell announces its arrival and the sliding doors open, releasing a wave of warm air from within.

The overhead speaker crackles to life, a disembodied voice announcing the next station, a beacon of information in the dimly lit cavern. The audio captures the essence of travelling by underground train, from the unique soundscape
